What will be the new position of the point (−8, 4) when rotated through 90° anti- clockwise about the origin?

i. (−4, −8) ii. (−4, 8) iii. (4, 8) iv. (2, 4)

we have

(x,y). rotation through 90° anti-

clockwise about the origin(-y,x)

point (−8, 4) when rotated through 90° anti-

clockwise about the origin(-4,-8)

Option.i. (−4, −8)

step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
